Hello. Quick question about dragonettes. I have had a spotted mandrain for a 6 months now and after about a month of adding copepods to my tank I have sucessfully been able to get him to eat brine shrimp and bloodworms. I recently purchased a green madrain as well and he is also eating very well. My question is: is it completely necessary that I keep on adding copepods for these guys. I feel like they are getting all the nutrition they need with frozen food. Copepods are expensive. Thanks
